Some tips for using pry to experiment with test code:
Sandbox
Run this to get a sandbox test environment:
rails console --help
Usage: rails console [environment] [options]
-s, --sandbox Rollback database modifications on exit.
-e, --environment=name Specifies the environment to run this console under (test/development/production).
Default: development
--debugger Enables the debugger.
Thus use this for testing:
rails console test --sandbox
Load helpers
You can run this and all your helpers are available
require "rails_helper"
